Definitions
- the present disclosure relates generally to surgical accessories. More specifically, the present disclosure relates to a surgical mirror for improving the field of view of a surgical site.
- surgical assistants help to keep the surgical site clear by holding organs out of the way using retractors and other medical instruments. For example, during cholecystectomies, an assistant may need to retract the liver or gall bladder out of the way as the surgeon works. Alternatively, during splenectomies, the assistant may need to retract the diaphragm or other tissues out of the way.
- assistants have limited field of view due to the nature of the surgery, their position relative to the surgeon, etc. For example, in some cases, the surgeon's hands or head may block the field of view for assistants. Consequently, it is difficult to see what the surgeon is doing.
- an assistant needs to be aware of what the surgeon is currently doing in order to know what action to take next. For example, if the assistant is holding certain tissues out of the way, the assistant may need to manipulate the tissues in a certain direction so that the surgeon can advance to the next step.
- the assistant may be imperative that the assistant hold the tissue in a particular manner so that the surgeon does not inadvertently cut healthy tissue.
- U.S. Pat. No. 4,138,083 to Spiegel discloses a demonstration mirror that exemplifies the general need to improve visualization of open surgical procedures.
- the disclosed device is primarily designed to allow a large number of people in a remote gallery to view a surgical site. As a result, the device requires relatively large dimensions.
- the device is also heavy, bulky, and awkward. Such a device is not designed for improving the field of view of an assistant in close proximity to the surgeon.
- the present disclosure overcomes drawbacks of the prior art by providing a surgical mirror assembly that improves the field of view of a surgical site for one or more assistants.
- An improved field of view is enabled by a small, adjustable surgical mirror assembly placed adjacent to or partially in a surgical site to reflect an unobstructed view of the surgical site as a surgeon works.
- the present disclosure also overcomes drawbacks of the prior art by providing a simple and inexpensive device for improving the field of view for an assistant in close proximity to a surgical site.
- the disclosure provides a surgical mirror assembly for facilitating observation of surgical procedures, the mirror assembly comprising a holder and a mirror, wherein the mirror is coupled to the holder in an adjustable manner.
- the holder includes a superior portion for resting on a patient surface adjacent a surgical site and a medial portion for hanging at least partially in the surgical site; wherein the mirror is coupled to the superior and medial portions of the holder in an adjustable manner to improve a field of view of the surgical site.
- an assistant using a retractor or other surgical instrument may observe a reflected view of the surgical site as the surgeon works.
- the mirror and holder may be placed anywhere adjacent to the surgical site so as to improve the field of view for the assistant.
- the position of the mirror and holder may depend on the position of the surgeon and the assistant with respect to the surgical site. For example, if the surgeon's hands are straight out in front as he works, the mirror may be placed behind, or to the side, of the surgeon's hands so as to reflect what is taking place in between without interfering with the procedure. By positioning the mirror slightly in the surgical site, a view from underneath the surgeon's hands or arms may also be obtained.
- the superior and medial portions of the holder include one or more coupling mechanisms (such as hooks, tabs, etc.) for supporting the mirror.
- the mirror includes a medial rod coupled to a bottom portion of the mirror and a superior rod coupled to a top rear portion of the mirror.
- the medial rod may be coupled to the medial portion of the holder and the superior rod coupled to the superior portion of the holder.
- the superior portion of the holder also includes a mechanism for securing the holder to an opening of a fenestrated surgical drape adjacent to the surgical site.
- One advantage of the disclosed surgical mirror assembly is its ability to improve the field of view for an assistant. Thus, the need for assistants to crowd closely to the surgeon to view the surgical site is avoided. Moreover, an assistant can view what the surgeon is doing and thus be aware of what action is required, and when.
- Another advantage of the disclosed surgical mirror assembly is its ability to be quickly and easily adjusted to improve field of view. As a result, if the surgeon or assistant change positions, the mirror may be easily readjusted without interfering with the surgical procedure.
- the disclosed surgical mirror assembly is that it is small, simple, and inexpensive and thus may be readily implemented.
- a further advantage of the disclosed surgical mirror assembly is that it may be readily sterilized for reuse.
- the surgical mirror assembly may be designed for single use.

Description
- 1. Field of the Disclosure
- The present disclosure relates generally to surgical accessories. More specifically, the present disclosure relates to a surgical mirror for improving the field of view of a surgical site.
- 2. Background of the Disclosure
- Traditional open cholecystectomies (removal of the gall bladder) and splenectomies (removal of the spleen) are typically performed through an incision in the abdomen to allow a surgeon to directly access underlying organs. Such incisions may range anywhere from four to seven inches in length or more depending upon the particular patient. Today, although laparoscopic techniques have replaced many open procedures, such less invasive techniques are not always feasible. In some cases, laparoscopic surgeries end up being converted to open surgeries for various reasons. Some reasons for performing open surgeries include: limited or obscured laparoscopic field of view, abdominal peritoneal adhesions, extensive scar tissue from previous surgeries, planned bile duct exploration, high BMI, or unavailability of laparoscopic equipment. As a result, there remain many surgeries that are still performed using conventional open techniques.
- During open surgery, surgical assistants help to keep the surgical site clear by holding organs out of the way using retractors and other medical instruments. For example, during cholecystectomies, an assistant may need to retract the liver or gall bladder out of the way as the surgeon works. Alternatively, during splenectomies, the assistant may need to retract the diaphragm or other tissues out of the way.
- One common problem with open surgical procedures is that assistants have limited field of view due to the nature of the surgery, their position relative to the surgeon, etc. For example, in some cases, the surgeon's hands or head may block the field of view for assistants. Consequently, it is difficult to see what the surgeon is doing. However, for a procedure to be as efficient and effective as possible, an assistant needs to be aware of what the surgeon is currently doing in order to know what action to take next. For example, if the assistant is holding certain tissues out of the way, the assistant may need to manipulate the tissues in a certain direction so that the surgeon can advance to the next step. In addition, during critical steps of a procedure, it may be imperative that the assistant hold the tissue in a particular manner so that the surgeon does not inadvertently cut healthy tissue. However, if the assistant is unable to see what is happening, it is difficult to anticipate what the surgeon will do next or to effectively manipulate tissue in a critical manner. Sometimes one or more assistants end up crowding closely to the surgeon in order to view the surgical site. However, this is undesirable as such crowding hinders the surgeon, obscures the field of view for others, and/or causes instruments held by assistants to shift.
- U.S. Pat. No. 4,138,083 to Spiegel discloses a demonstration mirror that exemplifies the general need to improve visualization of open surgical procedures. However, the disclosed device is primarily designed to allow a large number of people in a remote gallery to view a surgical site. As a result, the device requires relatively large dimensions. In addition, the device is also heavy, bulky, and awkward. Such a device is not designed for improving the field of view of an assistant in close proximity to the surgeon.
- What is needed, therefore, is a simple adjustable mirror assembly for improving the field of view of an open surgical site so that an assistant can effectively see what the surgeon is currently doing. There is also a need for a surgical mirror assembly for observing a surgical site that is relatively small, inexpensive, and may be readily implemented. There is further a need in the art for a surgical mirror assembly for observing a surgical site that enables safer, more efficient, and more effective open surgical procedures.
- The present disclosure overcomes drawbacks of the prior art by providing a surgical mirror assembly that improves the field of view of a surgical site for one or more assistants. An improved field of view is enabled by a small, adjustable surgical mirror assembly placed adjacent to or partially in a surgical site to reflect an unobstructed view of the surgical site as a surgeon works. The present disclosure also overcomes drawbacks of the prior art by providing a simple and inexpensive device for improving the field of view for an assistant in close proximity to a surgical site.
- According to a preferred aspect, the disclosure provides a surgical mirror assembly for facilitating observation of surgical procedures, the mirror assembly comprising a holder and a mirror, wherein the mirror is coupled to the holder in an adjustable manner. Preferably, the holder includes a superior portion for resting on a patient surface adjacent a surgical site and a medial portion for hanging at least partially in the surgical site; wherein the mirror is coupled to the superior and medial portions of the holder in an adjustable manner to improve a field of view of the surgical site. As a result, an assistant using a retractor or other surgical instrument may observe a reflected view of the surgical site as the surgeon works. The mirror and holder may be placed anywhere adjacent to the surgical site so as to improve the field of view for the assistant. In addition, it is appreciated that the position of the mirror and holder may depend on the position of the surgeon and the assistant with respect to the surgical site. For example, if the surgeon's hands are straight out in front as he works, the mirror may be placed behind, or to the side, of the surgeon's hands so as to reflect what is taking place in between without interfering with the procedure. By positioning the mirror slightly in the surgical site, a view from underneath the surgeon's hands or arms may also be obtained.
- In embodiments, the superior and medial portions of the holder include one or more coupling mechanisms (such as hooks, tabs, etc.) for supporting the mirror. By providing a plurality of coupling mechanisms, the elevation and angle of the mirror may be readily adjusted to provide an optimal field of view. It is appreciated that the coupling mechanisms are located on an outer portion of the holder and therefore need not come into direct contact with the surgical site. According to further embodiments, the mirror includes a medial rod coupled to a bottom portion of the mirror and a superior rod coupled to a top rear portion of the mirror. In operation, the medial rod may be coupled to the medial portion of the holder and the superior rod coupled to the superior portion of the holder. In embodiments, the superior portion of the holder also includes a mechanism for securing the holder to an opening of a fenestrated surgical drape adjacent to the surgical site.
- One advantage of the disclosed surgical mirror assembly is its ability to improve the field of view for an assistant. Thus, the need for assistants to crowd closely to the surgeon to view the surgical site is avoided. Moreover, an assistant can view what the surgeon is doing and thus be aware of what action is required, and when.
- Another advantage of the disclosed surgical mirror assembly is its ability to be quickly and easily adjusted to improve field of view. As a result, if the surgeon or assistant change positions, the mirror may be easily readjusted without interfering with the surgical procedure.
- Yet another advantage the disclosed surgical mirror assembly is that it is small, simple, and inexpensive and thus may be readily implemented.
- A further advantage of the disclosed surgical mirror assembly is that it may be readily sterilized for reuse. Alternatively, the surgical mirror assembly may be designed for single use.

mirror 32 and holder 20 may depend on the position of the surgeon and the assistant with respect to thesurgical site 18. For example, if the surgeon's hands are straight out in front as he works, themirror 32 may be effectively placed behind, or to the side, of the surgeon's hands so as to reflect what is taking place in between without interfering with the procedure. - The
mirror 32 may be comprised of various materials, including polished metal, stainless steel, plastic, glass, or the like. For example, polished stainless steel mirrors for surgical devices are disclosed in U.S. Pat. No. 5,349,943 to Ruiz. Themirror 32 may further be comprised of multiple layers as will be appreciated by those skilled in the art. Moreover, possible mirror configurations include, but are not limited to: rectangular, circular, oval, parabolic, and triangular shapes. - In embodiments, the

In embodiments, thesupport 36 comprises an arm pivotally coupled to themirror 32 using e.g., a hinge, ball joint, or other equivalent device. For example, by using a ball-joint, rotation of the mirror may be achieved in two or more directions. In other embodiments, thesupport 36 is a metal ball chain, or other flexible device for supporting themirror 32. Also shown inFIG. 3 a, is a medial rod 38 (shown in cross section) coupled to a bottom portion of themirror 32. In embodiments, themedial rod 38 is also coupled to themirror 32 using one or more hinges, ball joints, etc. -
FIG. 3 b depicts a rear view of themirror 32. As shown inFIG. 3 b, themedial rod 38 is longitudinally disposed adjacent a bottom portion of themirror 32, and thesuperior rod 34 is coupled to the top rear portion ofmirror 32 via support 36 (not shown). - In operation, the
mirror 32 is adjustably coupled to the holder 20 by securing themedial rod 38 to themedial portion 26 of the holder, and securing thesuperior rod 34 to thesuperior portion 24 of the holder 20. In embodiments, therods equivalent coupling mechanism 28. Thus, if the assistant needs to adjust themirror 32, thesuperior rod 34,medial rod 38, or both, may be readily engaged with adifferent coupling mechanism 28 to adjust the viewing angle. By providing a plurality ofcoupling mechanisms 28 on the superior andmedial portions mirror 32 can be adjusted to provide an optimal field of view. In addition, by using e.g., ball joints to couple themirror 32 to support 36 and/ormedial rod 38, the angle of themirror 32 may be adjusted in two or more directions. - In embodiments, the
mirror 32 is comprised of: polished metal, stainless steel, plastic, glass, or the like. It is further understood that themirror 32 may be comprised of a plurality of layers, including various protective coatings. Such layers may be disposed on the mirror surface e.g., by vapor deposition or other conventional manufacturing techniques. Examples of protective coatings include, but are not limited to: anti-glare or anti-reflective coatings, anti-fogging coatings, and scratch-resistant coatings, as will be appreciated by those skilled in the art. In some cases, scratch-resistant coatings may be desirable to protect from damage by surgical instruments. Preferably, the coatings are able to withstand chemicals, high temperatures, high pressures, etc. used for sterilization. Alternatively, the materials are suitable for one-time use and are therefore disposable. - The size and shape of the
mirror 32 may vary depending upon the intended surgical application. Preferably, the dimensions of themirror 32 are sufficiently small to fit at least partially within the surgical site while providing an improved field of view for one or more assistants. In embodiments, the mirror is designed to be planar or curved. For example, aplanar mirror 32 can be used to provide an image of a surgical site with a one-to-one ratio. In another example, a slightly concave orparabolic mirror 32 can be used to provide a wider field of view of the surgical site. It is appreciated that themirror 32 may further be designed to provide other magnification ratios as will be appreciated by those skilled in the art. Moreover, possible mirror shapes include, but are not limited to: rectangular, circular, oval, parabolic and triangular. - It can be seen from the above discussion that the disclosed surgical mirror is able to provide improved visibility of a surgical site for one or more assistant. Such capabilities are enabled by an adjustable mirror placed adjacent to or slightly in a surgical site for reflecting a view of the site as a surgeon works. Preferably, as discussed above, the mirror can be adjusted in elevation, angle, and/or rotation to provide an optimal field of view.
- By providing improved field of views, the
surgical mirror assembly 10 of the present disclosure can improve speed and accuracy of open surgical procedures. As a result, the surgical mirror is able to provide safer and more effective results while additionally saving time by enabling an assistant to anticipate a next required course of action. - The foregoing disclosure of the preferred embodiments of the present disclosure has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many variations and modifications of the embodiments described herein will be apparent to one of ordinary skill in the art in light of the above disclosure. While not limited to any particular use, it is envisioned that the
surgical mirror assembly 10 is advantageous for use in abdominal surgeries such as gall bladder surgeries, splenectomies, etc. However, thesurgical mirror assembly 10 may be used in other surgical procedures such as prostate surgeries, urinary bladder resection, and more. In addition to improving fields of view for surgical assistants, thesurgical mirror assembly 10 may also be used to improve the field of view for additional surgeons or other observers in close proximity to the surgical site. It is further envisioned that the size and shape of thesurgical mirror assembly 10 may be varied depending upon the type of surgery or application of use. For example, the holder 20 and/ormirror 32 may be designed to be larger for obese patients, and smaller for younger patients. In embodiments, the holder 20 may be composed of a flexible or pliable material so that it may be conformed to the patient and/or surgical site for good surface contact. Moreover, the shape of the surgical mirror may assume various shapes depending upon the type or surgery or application. The disclosedsurgical mirror assembly 10 may further be used with any suitable light source to provide improved illumination of the surgical site. Accordingly, the scope of the disclosure is to be defined only by the claims appended hereto, and by their equivalents.
